"don't have any low end torge, runs like hell after 3000 RPM"
Classic symptom of too much cam for the available static compression ratio.
"have 188.8.131.52 compression pistons."
There is no such thing as 9.5 pistons or 10.5 pistons or 11.5 pistons or any other "stated as such and such compression ratio" pistons. Static compression ratio is a function of cylinder volume, piston deck height volume, piston crown volume, head gasket volume and combustion chamber volume.
